Been doing this for 18 months. Pro tips from experience:
- Buy a pack of 29g or 30g insulin syringes for injection — thinner = less pain
- After reconstitution, I put a tiny piece of tape on the vial with the date and concentration written on it
- If you see bubbles after swirling, just let the vial sit for 5 minutes. They'll dissipate.
- When drawing your dose, insert the needle, invert the vial, and pull back PAST your desired dose, then push back to the exact line. This helps clear any air bubbles in the syringe.
It becomes second nature after 2-3 times. Promise.
